Creating Document Map in SSRS

Document Map makes navigation is easy to navigate through table in SSRS

1. In our case we have dataset which contains Product and Product Subcategory. We created the 2 parent groups on Product key and Product Subcategory key.
   
2. We have to go in the Parent group(ProductCategoryKey) >Advanced > Document Map and select the column used for document Map, in our case we are using ProductCaegoryName
   
3. Go to Tablix property and in the Document Map Label and specify the Document Map Name.
   
4. When we preview the report we can see the Product Index Label under the Document Map as shown in image, we can navigate though the table from the Product index.
5. 

In this way we can create document Map in SSRS to navigate through the report.
